Introduction
The engine control system on the diavel uses a sensor that measures the temperature of the coolant (engine temperature). This sensor has a resistance of ntc type (negative temperature coefficient), that reduces its own value when the temperature increases. The engine temperature sensor, allows the control unit to manage correctly the cold starting and the heating phases.
Components assembling position
The engine temperature sensor is mounted on the left hand side of the vertical cylinder.
Location of engine temperature sensor connector.
Wiring diagram
Ccm engine control connection, s engine temperature sensor. 1 Green/white - g/w, 2 black/purple - bk/v.
In the event of fault
In the event of an engine temperature sensor fault, the engine control unit implements a recovery value of 70C and activates the radiator fans.
Fault codes generated and possible correlated faults
Fault codes generated by the engine control unit and displayed by the dds (engine temperature sensor diagnosis):
Note
Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.
Check integrity of electric circuit - short-circuit to ground = with the battery cables disconnected, using an ohmmeter, continuity is detected between the wire tested and ground.
Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.
The tank dashboard shows the error "engine temperature" and the eobd warning light activates.
When the dashboard receives the "engine temperature" error, flashing dashes are displayed instead of the temperature reading. If the dashboard does not receive engine temperature information from the can line, the error "engine temperature" is not shown on the display, but flashing dashes are still displayed instead of the temperature reading.
Possible correlated faults: inadequate engine power, irregular idle speed (target idle speed is 1350 rpm with engine stabilised at operating temperature), the engine does not start easily, radiator fans not activated correctly or not activated at all, causing the coolant to reach boiling point.
Check:
The engine temperature value may be checked using the dds. Check that the value given is plausible.
If none of the aforementioned tests identify the problem and the engine temperature sensor is in proper working order, replace the engine control unit.
component replacement methods
No special measures are necessary in order to replace the engine temperature sensor. After replacement of the engine temperature sensor, reset the self-adaptive parameters relative to carburation with the dds.

Disassembly of the rear brake control
The brake master cylinder is supplied only as a complete unit; internal
components cannot be replaced.
To disassemble the master cylinder's outer parts, follow the indications given
in the exploded view at the beginning of this
section.

Note
Helmet cable (2, fig. 104) Can be found inside the tool
kit, see "tool kit and accessories" on page 141.
Pass the cable through the helmet and insert the end of the
cable in the pin (3, fig. 104). Leave the helmet hanging and
refit the seat to hold it in place.
